The scenario has the players taking part in an exploration mission to a planet that was sealed off because of a shield surrounding it which recently began to crack open. Landing on the planet, the players find no signs of life although there are plenty of signs of life having previously been there. The group meets up with an advance scouting party, who explains some of the points of interest in the area. The group then gets to investigate those points of interest and learn what they can based on some skill checks. The familiar PF2e 4 degrees of success comes into play as the players earn Survey Points based on their success/crit successes. Once they've spent some time exploring, they report back to the scouting party with what they've seen in time. Just as they finish their brief, an event suddenly has an alien appear near them, as well as some basic life forms (birds, insects, etc) and a hostile creature which leads to the first combat. The creature has a mechanic which interacts with some floral hazards in the area so there's a few moving pieces in the fight to keep it interesting. The encounter itself is a moderate one and based on my experience playing PF2e, it felt like one; the group was never in danger but took some damage and was able to test out some abilities without worrying if they wasted a turn.
After that, they were encouraged to make their way to another location to see if they can stop the crumbling shield around the planet from falling apart completely. On the way, they had to deal with a hazard in the form of shards of energy falling from the sky and then were attacked by malfunctioning repair bots that was rated as a low encounter. The group took care of them in 2 rounds, which was good because they had an ability that mimicked the spell
Hydraulic Push which seemed potent for a level 1 low encounter. It does say only 1 of the bots will use it per round and only 1 managed to get an attempt off that missed. The adventure then concludes as it just has you narrate the group arriving at their destination and succeeding in their mission. The ending felt very "let's wrap this up, we're pushing 2 hours with this and it's a SFS scenario" but maybe that's the norm for PFS/SFS scenarios.
